Xata
PostgreSQL platform offering instant database branching, cloning any Postgres database in seconds using copy-on-write storage.
About
Xata is a PostgreSQL platform built around instant database branching for development workflows. The company says teams can clone any Postgres database in seconds regardless of size, using copy on write storage.
Rather than full copies, each branch shares data with its parent and stores only changes. Branches scale to zero, waking on first query and responding instantly. The service runs 100% upstream PostgreSQL without significant modifications, with no forks and no proprietary APIs.
Target use cases are isolated databases for coding agents during testing, fresh Postgres branches for CI/CD pipelines and pull requests, and dedicated databases for generated applications. The pitch is a large reduction in compute and storage overhead compared with traditional staging database approaches.
